-To reach an asset that belongs to another package, use `package:` URLs in
-Dart code, but in any other language (like HTML or CSS) use relative URLs that
-first go all the way to the `packages/` directory.

-URLs that refer to assets in other packages need to explicitly mention the

-now you must use a canonical URL form for it.

-For example, if `packages/a/a.html` needs to import `packages/b/b.html`,
-you might expect a.html to import `../b/b.html`. Instead, it must import
-`../../packages/b/b.html`.
